Atorvastatin Side Effects, Usefull Information, Upsides & Downsides

Atorvastatin is from a class of drugs known as HMG CoA reductase inhibitors, or simply as statins. Atorvastatin’s therapeutic action is to lower the levels of low-density lipoproteins (LDLs, also commonly known as bad cholesterol) and fats and increases the levels of high-density lipoproteins (HDLs, commonly called good cholesterol) in the body. Atorvastatin lowers the levels of these LDLs and fats by inhibiting their production by the liver. Decreased levels of LDLs and increased HDLs are known to reduce the risk of heart diseases and to prevent strokes and heart attack. Atorvastatin is approved for use in adults and children of age 10 or older.
